The modulus of complex number can be computed with this equation:
|z|=sqrt(Re(z)^2+Im(z)^2)
z = -2-6i
Re(z)=-2, so Re(z)^2=4
Im(z)=-6, so Im(z)^2=36
|z|=sqrt(36+4)=sqrt(40)=6.3
Since 30 is not a square root you would use the closest square roots √25 and √36 which makes your answer 5 and 6
7.20+24.75=31.95
so 31.95 per student
31.95*350=11,182.50
This will cost the student body $11,182.50
Move ABCD 3 units to the left and 2 units up. (x-3, y+2)
Divide 42 by 30 and that should be your correct answer.
hope this helps.
